Patent Images
1. A head mounted display device comprising:
- a display panel displaying an image restored from an image record medium;
a bar type prism having a first flat tilted surface, a second flat tilted surface, and a flat total internal reflection surface, the bar type prism reflecting light emitted from the display panel to an eye of an observer through the flat total internal reflection surface, the first flat tilted surface totally reflecting the light reflected from the flat total internal reflection surface to the eye of the observer through the flat total internal reflection surface; and
an eyepiece lens opposing the flat total internal reflection surface of the prism without inclination so as to display an enlarged virtual image in front of the observer.

8. A head mounted display device comprising:
-
a pair of display panels respectively correspondent to the left and right eyes of an observer; a signal processor controlling a signal applied to the display panel; a bar type prism having a first flat tilted surface, a second flat tilted surface, and a flat total internal reflection surface, the bar type prism reflecting light emitted from the display panel to an eye of an observer through the flat total internal reflection surface, the first flat tilted surface totally reflecting the light reflected from the flat total internal reflection surface to the eye of the observer through the flat total internal reflection surface; and
